| Parkinson's disease produces changes in cognitive as well as motor areas of the brain, Dutch neuropathologist Heiko Braak and his colleagues reported in 2003. This is because the SMC regions are important for supporting move-merit initiation and fine motor coordination (primary motor cortex [M1] (27,28)), transitioning between movements (premotor cortex [PMC] (29)), and the selection of responses in a sequence when choices are based on internal or prelearned information (supplementary motor areas [SMA] (30)). Unfortunately, children with DCD may experience problems not limited to fine or gross motor areas. |
